摘要:

介绍了针对四拼数码航空相机的附加约束条件光束法区域网平差原理,包括计算四拼相机外方位元素,并同时计算四台子相机的相对位置关系,获取四拼相机平台检校参数。实验结果表明采用这种方法计算出来的平台检校参数精度高,生成的虚拟影像拼接效果好,测图精度满足大中比例尺地形图规范要求。

Abstract:

The method of bundle block adjustment with conditions aims at the four-head aerial digital camera is discussed. The exterior orientation parameters of camera and relative positions of sub-cameras are calculated to derive platform calibration parameters. The experiment results verified that the precision of platform calibration parameters calculated with this method is high, the quality of virtual images are good, and the mapping precision satisfies the large scale and medium scale specifications of survey.
